All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the original MAX1248BEEE device.

Parameter Comparison

Engineering Selection Recommendations

MAX1248BEEE+ (Direct Substitute): The MAX1248BEEE+ is the primary substitute for the obsolete MAX1248BEEE. Both parts share identical electrical and mechanical specifications. The MAX1248BEEE+ is currently in active production status and is RoHS3 compliant, making it suitable for new designs and legacy system updates. The packaging format is Tube, which differs from the original bulk packaging but maintains the same component specifications.

MAX1248AEEE+ (Parametric Equivalent): The MAX1248AEEE+ is a parametric equivalent offering identical electrical performance and mechanical compatibility. This part is also in active production and RoHS3 compliant. Selection between MAX1248BEEE+ and MAX1248AEEE+ should be based on availability, lead time, and supplier inventory levels, as both parts meet all functional requirements.

Both substitute parts eliminate the obsolescence risk associated with the original MAX1248BEEE while maintaining full electrical and mechanical compatibility for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can MAX1248BEEE+ and MAX1248AEEE+ be used interchangeably with MAX1248BEEE?

A: Yes. Both substitute parts maintain identical electrical specifications including 10-bit resolution, 133 kSPS sampling rate, 2/4 configurable input channels, SPI interface, and -40°C to 85°C operating temperature range. Mechanical compatibility is preserved through identical 16-SSOP packaging and surface mount configuration.

Q: What is the difference between MAX1248BEEE and MAX1248BEEE+?

A: The primary differences are product status and compliance certification. MAX1248BEEE is obsolete and RoHS non-compliant, while MAX1248BEEE+ is in active production and RoHS3 compliant. Electrical and mechanical specifications are identical. Packaging format differs (bulk versus tube), but component performance is equivalent.

Q: Are there any supply voltage or temperature range limitations when substituting?

A: No. All substitute parts operate across the identical supply voltage range of 2.7V to 5.25V for both analog and digital supplies, and maintain the same -40°C to 85°C operating temperature specification.

Q: Does the SPI interface remain compatible across all substitute parts?

A: Yes. All parts utilize SPI as the data interface with identical protocol implementation, ensuring direct compatibility with existing firmware and hardware interfaces.

Q: What packaging considerations apply to these substitutes?

A: All parts use 16-SSOP surface mount packaging with 0.154" (3.90mm) width. PCB footprints and reflow soldering profiles remain identical across all variants.
